Is there a way to delete the delay between MP3 tracks? When I play a mixed "CD" in Mp3 format through xboxmediaplayer there is a little silence between each track.

Dont think there is at the minute but im sure they are working on a way to read the disk as a .cue file to allow gapless playback. That will only work for audio cds. Data cds with mp3s on i dont think so.
